DOUBLE-HUNG WINDOW.

Application filed March 17, 1926.

' This invention relates to double hung windows and is in the nature ofan improvement on the class of windows shown in my United States PatentsNo. 1,459,668 of June 19, 1923 and No. 1,512,741 of Oct. 21, 1924.

The present invention and improvements are directed to features of sill;lower sash stile; parting. strip, and sliding sash members, as morefully described hereinafter.

In the accompanying drawings forming a part hereof and illustrating thisinvention,

Fig. 1 is an interior, elevational View of a metal window frame andmetal sash assemblage embodying the present invention.

Fig. 2 is a Vertical, elevational View partially in vertical crosssection at line 22 of Fig. 1; and

Fig. 3 is a transverse, horizontal View partially in horizontal crosssection at line 33 of Fig. 1.

In Fig. 2 the illustration is broken into three parts by wave-d lines.It is to be noted that the structure of the two opposed sides of thewindow frame are of identical construction and therefore that only oneside as illustrated in Fig. 3 is described. Similarly the two verticalsides of each sash are of identical construction and only one side isdescribed.

Referring to the drawings:

Window frame c0nstmcti0n.-The metal window sill (Fig. 2) has adependent, interior flange 1 the upper portion of which extends into aflat, horizontal ledge 2 at theoutward side of which there is adownwardly extending shoulder 3 that merges into a horizontal sillportion 4. Following the structure outwardly in the direction of theoutside of a building, sill portion 4 merges into a vertical wall 5which forms the in terior side of a trough 6 the outward wall of whichis a joint wall 7. From this joint wall the upper surface of the sillslopes downwardly and outwardly at 8 and terminates in a shoulder 9which overhangs a drift water receiving cove 10 formed by a forwardlyprojecting bend a of the metal below shoulder 9. From bend a the sillextends outwardly and downwardly at 11 and terminates in an outward orexterior, dependent flange 12. The sill is a one piece metal structurewhich extends transversely along the bottom of the window frame.

Each of the two front interior, vertical stop moldings has its under andagainst an Serial No. 95,251.

being held to the underside of a transverse,

horizontal, top jamb 16 having a front, up-

wardly extending flange 17 which terminates in a iorizontal flange 18for engagement with structural material. Outwardly of flange 17, topjamb 16 is ofl'set to form on its underside a three-walled, transverserecess 19 for reception of the upper portion of a transverse, horizontalparting strip. Outwardly of recess 19 the top jamb has a portion 20 theunder surface of which forms an upper stop for the outside, upper sash.Portion 2O merges, in the outward direction, in a downwardly extendingwall 21 which merges with a flat, horizontal portion 22 that outwardlymerges with an upwardly extending portion 23 which terminates in a bentend 24 for engagement with structural material and forming a receptivespace for caulking between metal jamb and the masonry and opposedly tothe bent interior end 18.

The open side of the top stop molding 14 is next the under side of thetop jamb 16, and has an outward vertical wall 25. The recess 19, alongthe under side of the top jamb 16, receives the upper end portion of across sectional, quadrangular, horizontal, top parting strip having aninward, horizontal, transverse wall 26 and a parallel back wall 27. Thiscross sectional, quadrangular parting strip is chambered, its upper endis entrant in recess 19 and it is clamped in place by a screw 28.

At each of its vertical sides, one of which is shown at Fig. 3, thewindow frame structure is provided with a vertical, three-sided, sheetmetal, weight-pocket receiving member 29 having vertical parallel sides30 one of which terminates in an inward hook 31. Theoutward or rearwardside 30 terminates in a hook 32 The hooks serve as anchorages instructural material.

Hook 31 receives the forwardly turned, flan e 33 of a vertical, rightangular, side jamfi member having a. front portion 34 and a theretoright angularly, rearwardly extending portion 35. 4

Hook 32 receives the outwardly turned flange 36 of a vertical side jambmember which has an outside forming portion 37 parallel to portion 34.Portion 37 merges into a forwardly turned, straight portion 38 whichmerges into a portion 39 bent in the direction of the weight-receivingpocket. Portion 39 merges into a forward, turned, bent portion 40 whichis transversely alined with the portion 35 of the front member Theopposed ends of said portions 35 and 40 are spaced apart and connectedtogether by a vertical jamb plate 41. Each vertical edge of this plateis offset, the front offset, overlapping portion 35 and the rear offsetportion 42 overlapping the portion 40. The offset ends are secured tothe overlapping portions by screws 43 and the inward, vertical surfacesof the assemblages face towards the window frame opening.

The inward stop molding 13 is clamped to portion 35 by a screw 45 andoffset margin 42 is similarly clamped to ortion 40 by a screw 43. Eachmolding 13 as an inwardly and laterally projecting, vertical wall 44which forms the front wall of a vertical, front sash receiving groove.Wall 44 is parallel to and spaced apart from the vertical wall portion39 and wall 39 forms the outward vertical wall of an outer sashreceiving groove.

J amb plate 41, between its vertical margins, is offset to form avertical groove 46 for reception of a side of a vertical parting strip47 which is clamped in the groove by a screw 48. Each vertical partingstrip 47 is oppositely formed, on its forward and backward sides, with alengthwise "extending, vertical groove 49 for reception of sash members.The under, forward sash is thus vertically movable between the stopmolding wall 44 and the bottom of the forward groove 49, the upper andoutward sash being movable between the rearward wall of the bottom ofthe rear groove 49 and the wall 39.

The weight receiving chamber is indicated by 50, the back weight for theupper sash by 51, the back weight for the under sash by 52 and avertical weight separator by 53.

Looking at Fig. 2, it will be seen that the inward surface of verticaljamb plate 41 forms the bottom of the vertical groove in which the edgeof the under, forward sash slides, while Fig. 3 shows that the inwardand flush surfaces 54 of portion 40 and of plate 41 form the bottom ofthe groove in which an edge of the upper and outer sash slides.

The under end of parting strip 47 is beveled outwardly and downwardly at47; the under end of portions 40, the inward side of which forms thesurface 54, is also slanted outwardly and downwardly at 54", and theunder end of the outer portion 38 is similarly slanted downwardly andoutwardly at grooves.

38 so that these three members severally bottom on and bear against thedownwardly and outwardly slanting sill portion 11.

Novel features of the window frame structure are the shoulder 3 toprevent water of condensation on the inside of the under sash fromrunning out into the room over the front of the sill; the groove 6 withits wall 7 for receiving the under, front corner flange of the undersash and form, contact between the sill and sash; the shoulder 9 abovethe drip or drift water cove 10 for contact with an under, rear cornerflange of the under sash; the vertical parting strip 47 with its opposedside grooves, each for reception of a projecting sash member whereby,when in operative installation, there will be an air chamber on eachside of the sash projection,

forming pockets between the sash projection and the outward edges ofthe-grooves-of the upper and of the vertical parting strips.

The vertical the parting strips 47 serve in an important way to receivedriving water from storms and to prevent it from leaking inwardly pastthe lower sash in its closed position, because such water is conducteddownwardly and discharged on the sill portion 11 by such The grooves 49,both front. and back, discharge downwardly and outwardly on the sillportion 11. Sill portion 8 is preferably formed with weep holes 8communicating with drift-water cove 10.

Lower sash constructi0n-.The lower and interior sash for glass 60comprises a three flanged, chambered bottom frame the upper wall 61 ofwhich has a front, vertically dependent, transversely extending flange62 the under end of which, as the sash is lowered,

contacts with wall 7 of groove 6 and makes a weather tight joint betweenthe cam wall 7 and the sill. Upper wall 61 also has a dependent,vertical, transverse flange 63 which, when the window is closed down,contacts with the shoulder 9 and makes a weather tight joint by suchcontact, coming into contact with shoulder 9 before flange 62 contactswith wall 7 and drawing flange 62 into hard contact with wall 7. Theflanges 62 and 63 are so spaced apart that weather tight joints areformed by the two lines of close contact at shoulder 9 and wall 7. Thebottom of chamber 64 is formed b the downwardly and outwardly inclined,sill portion 8. all 61 also has an upwardly extending, verticaltransverse flange 65 which serves as an abutment for the outer side ofglass 60. The glass holding means are old and need not be described.

This under sash comprises at its upper end a top sash member 66 which isformed at its upper, front corner portion, forwardl of the plane of therear side of glass 60 with a transversely extending, open top trough 67.bottom wall of the trough is formed by rooves 49 at the outer side of ahorizontal, transversely projectingffiange 68 that terminates in anupstanding flange 69 which forms the front wall of the trough. The backwall of the trough is formed by the front side of sash member 66 abovethe bottom trough Wall 68.

A three sided channel bar 70 has its under, open side opposed to bottomwall 68 and is located between the front and back walls of the troughand clamped in the trough by a screw 71 through the upper wall of thechannel bar and entrant in the bottom trough wall 68. Sash member 66,outwardly of the troughwall 68, has considerable thickness. Its underside has a lengthwise extending groove 72. The back surface 73 of thesash member 66 is vertical from the under edge 74 of the rear wall ofgroove 72, the latter being for reception of a non-contacting,transverse flan e 75 which extends upwar lyand forwardly from thetransverse under =mrnloer 76 of the upper sash along the bottom of theupper and outward sash, holding glass 77. In consequence of thenon-contact between the flange and walls of the groove 72, an air pocketis formed between them. Said sash member 76 has a front, fiat wallmaking a tight joint with surface 73 when the upper and under sashes areclosed. Member 76 has a rear, dependent flange 78 which is parallel toits forward, downwardly projecting flange 79 from which the upwardly,forwardly extending flange 75 extends.

The upper and outward sash is provided with a three walled, open sided,rectangular air chamber forming member the bottom wall of which isindicated by 80. It has spaced apart, vertical, upwardly extending sides81 and 82. Side 82, when the sash is up, contactslwith the back wall 27of the upper, transverse parting strip. The rear wall 81 then contactswith screws or other .splavefl shape against portion 21 of the jamb plae16, being a means of pressing the sash against portion 21 to make anairtight joint.

Each vertical edge (Fig. 3) of the under sashjisprovided with avertical, three sided sash member 85 provided with a vertical,rearwardly projecting rib 86 which moves freely in the front slot 49 ofa vertical parting strip 47. Each vertical side of the upper, outwardsash is provided with a vertical, three walled, sash member 87 having aforwardly extending rib 88 that works freely in the rear groove 49 ofvertical parting strip 47. Thus the two chambers referred to are formedon each side of each of the two parting strips 47.

Important features of the sash structure are: the flange 62 that closesdowninto the -groove 6 to make a weather tight joint there-- at, and-theflange 63 which is longer'than the therewith parallel, front flange 62;the projecting ribs 86 and 88 that slide in the recesses 49 with theirexposed edges in com tact with the bottom walls of the recesses andtheir sides out of contact with the side walls of the recesses, therebyforming at the front and back sides of each vertical parting strip,avertical air pocket and water guideway. Such water guideways are ofspecial importance because when driving rain strikes against the underclosed sash, when the upper sash is closed, water cannot pass betweenthe sides of the under sash and opposed frame members, but beingarrested in the inward direction by the break joint construction,arising from the rib and groove wall construction, flows downwardly andis discharged from the front and back open sides of the groove 49 on theoutwardly and downwardly sloping sill portion 11.

The sash members (Fig. 2) 66 and 76 with the air pocket at 72 form awater-tight and weather-tight joint when the sashes are in closedposition. The members 85 and 87 form air pocketed, weather-tight meansco operative with vertically opposed portions of the window frame, atboth vertical sides of the sash. The lengthwise extending cove 10insures the outward discharge of rain driving from the outside againstthe sashes and the downwardly and rearwardly sloping sill portion 11;and the weather and water tight joints at 7 and 9 prevent the drift ofdriven rain from passing the closed under sash onto the interior portionof the window sill. Thus the construction insures perfect wind and'water-tightness around all four edges of the sashes and also at contactof the members 66 and 76; the transverse rearwardly facing shoulder 3also preventing flow into the room of interior, water condensation.

The rib 86 is extruded from the back side of the vertical member 85 orstile of the under, sash rib 88 being similarly extended from the frontside of the'vertical member 87 or stile of the upper sash. The free edgeof each vertical rib 86 and 88 contacts with the bottom of its receivinggroove in the parting strip only when the sashes are drawn together bylocking the sash drawing and locking device 89. In Fig. 1, the device 89is shown in sash drawing and locking position for the upper and lowersash which are shown closed. The sash binders 90, also shown in Fig. 1,are in sash binding position; and one of them is shown in the sameposition in Fig. 3. When the two sashes are drawn and locked together,with the ribs 86 each in contact with a bottom wall of a groove 49 inthe parting strip, and a vertical air pocket and water way 49 is formedat each side of each rib. Moreover, an air and water-tight joint isformed between the free edges of each rib and the bottom wall of thegroove with which it is thus drawn into contact. In this position,

fill

there are clearances at 91; there being a vertical front clearance 91between the back wall 44 of molding 13 and the front wall 92 of themember or stile 85; and a rear clear ance between the back wall 93 ofthe upper sash member or stile 87. It is now to be noted that when thesash devices 89 and 90 are in unlocked positions, the sash naturallymoves back slightly; the clearances at 91 are partially reduced, thecontacts of the ribs 86 and 88 relieved, and slight clearancesestablished between the parting strip and the walls 87 and 94 of the twovertical stiles 85 and 87. In such loose positions, both sashes arefreely raisable and lowerable and friction joints, during sash raisingand lowering movements, between the parting strips and sash stilesareavoided. This obviates sticking of the sashes in their guideways andrenders it easy to raise and lower these heavy, metal sashes withoutstrain on the person lifting or lowering the sashes.

The sash drawing and locking device 89 and the sash binders 90 aredescribed in my 7 Patent No. 1,459,668 of June 19, 1923, in

which a double hung window is shown.

It is also to be noted that the upper wall 61 between the transverseflange 63 and flange 62 has a length which is substantially less thanthe distance between the front wall 7 of the sill groove 6 and the back,free edge of the shoulder 9 whereby, when the back flange 63 partiallycontacts, on a closing movement of the under sash, with the upper cornerportion of shoulder 9, and the flange 63 travels past the back, freeedge of shoulder 9, the two flanges 62 and 63 are sprung apart,slightly, by the socketing of the under portion of flange 62 in sillgroove 6, thereby tightly binding the flange 63 against the free edge ofshoulder 9 and making a transverse, weather-tight joint between theflange 63 and said shoulder 9; and also forming a tight joint betweenthe under edge portion of flange portion 62 and the sill groove wall 7.It is also to be noted that the back flange 63 is longer than the frontflange 62.

What I claim is: I

1. As a new article of manufacture, a metal window frame sill havingadjacent its inward edge a lengthwise and downwardly extending shoulder;rearwardly thereof, a lengthwise and downwardly extending groove;rearwardly of the groove, a downwardly and outwardly slanting portionterminating in a lengthwise extending shoulder overhanging and formingthe top wall of a lengthwise extending drift water receiving cove; theunder wall of the cove merging into a continuously flat rearwardly andcontinuous downwardly slanting portion of the sill; said top wall beingformed with a weep-hole.

2. In double hung, metallic sash and window frame structure, thecombination of an upper and a lower sash; a window frame provided withsash guideway; a sash look ing and drawing device; a vertical partingstrip projecting into each sash guideway between the guideway sides, theparting strip being formed on its front face and also on its rear facewith a lengthwise extending, wide, rib-receiving groove, and each sashbeing provided with a vertical, narrow lengthwise extending, jointforming rib on each side of its side member, each narrow rib projectinginto one of said wide grooves between the sides of the latter; theguideways being wider than the thickness of the side members to affordclearances; the sashes running freely in their guideways with the freeedges of said ribs out of positive contact with the bottoms of saidgrooves; said ribs forming lengthwise extending, weather-excludingpockets of substantial cross-sectional dimensions, in each guideway, ateach side of each rib; and said sash locking and drawing device beingoperative to force the free edges of said ribs into tight, joint-formingcontact with the groove bottoms when the device is locked and in sashlocking and drawing position; and a sill; the rearward pockets openingexteriorly and the forward pockets opening inwardly, above the sill fordischarge of water thereon.
